Description For EPDM Ethylene Propylene: The service temperature can be designed from -55°C to 125°C or up to 150°C (for peroxide cured systems). In phosphate-ester based hydraulic fluids and glycol based brake fluids systems Ethylene Propylene Rubber is good choice for sealing parts. Appling in domestic water, rubber parts must pass the chloramine and chlorine resistance test. It is not suitable for any types Ethylene Propylene Rubber, higher saturated EPDM or EPM and higher ethylene content will be well for chloramine and chlorine attacking. It also usually be used in hot water or steam up to 150°C. Ethylene Propylene Rubber is not suitable in petroleum fluid (fuels, mineral oils, greases) For FKM FPM Fluorocarbon: The general type the service temperature is better limited to approximately from -26°C(-15°F) to 232°C(450°F) in static application. Because FKM has excellent resistance of high temperature, oil, solvent, flame, chemical and weather, it is usually applied in automotive, chemical processing, aerospace and many industrial. For HNBR Hydrogenated Nitrile: The service temperature is from -40°C to 150°C and some special compound can up to 160°C. HNBR has wide applications in auto and oil industries. For environment requirement HCFC will be replaced by ozone-safe refrigerants-HFCs. In old air conditioning and refrigeration equipment Chloroprene (CR) and Fluoroelastomer (FKM) are popular material with coolant system of HCFC (or CFC) and mineral oil. But CR and FKM is not adequate in the newer coolant system HFC134a (R134a) and PAG lube, because CR will degrade PAG lube and FKM will swell more in R134a, the available rubber is HNBR. For NBR Nitrile: The service temperature can be designed from -55°C to 100°C or up to 125°C depending on different acrylonitrile content and formula. Generally higher than 100°C, life time will be shortened. NBR compounds have excellent resistance to abrasion, non-polar oils and solvent, water and permeation (higher acrylonitrile content will be better). NBR also can be used in conditions of dilute acids, alkalis and salt solution at low temperatures. For VMQ Silicone: The service temperature are from -60°C to 225°C. Some special types can be used in extreme temperature up to 300°C and down to -100°C. Silicone rubber performs well under environmental and temperature extremes, it usually be applied in automotive and aerospace industries, where flexibility and longevity are important. It also has outstanding electrical insulating properties, applying in strict performance standards are critical. And it is a suitable material for parts that need FDA approval for food handling equipment and appliances. For PU Polyurethane: The service temperature of PU is -40°C to 80°C, shortened lifetime up to 100°C. Polyurthane usually are applied in mechanical industry, especially in the place requires material must have higher wear resistance and higher strength. Some applying environment will happen moisture condensing on the surface of rubber seal, which will cause hydrolysis of AU, so choosing EU is better. But EU doesn't resist well to oil, the lubricant must use higher aniline point oil.
